Plates-the lithosphere broken into separate sections Scienctific theory-a well tested concept that explains a wide range of observations Plate tectonics-a geological theory that states that pieces of Earth's lithosphere are in constant,
slow motion, driven by convection currents in the mantle Faults-breaks in the Earth's crust where rocks have slipped past each other Transform boundary- a place where two plates slip past each other,moving in opposite directions Divergent boundary-a place where two plates move apart Convergent boundary-a place where two plates come together Rift Valley-a deep valley that forms where two plates move apart

Introduction
1965 J. Tuzo Wilson
Wilson thought the lithosphere was broken into pieces
pieces called plates.
the plates fit closely together
Theory of Plate Motion
formation
movement
subduction
Plate Boundaries
Transform boundary
Divergent boundary
Convergent boundary
Transform Boundaries
Earthquakes occur frequently along these boundaries
